I moved away from home when I was around 22 years old . I lived out of state from my family and tried to visit as often as I could. I returned one summer for a week of relaxation and rest . My parents were working as was my brother . My sister and her friends were laying on the deck working on their tans and all I could do was peek out the bathroom window and fantasize about my sisters friends . I was 26 years old and they were 18 just out of high school.
I was getting in to the shower when my sister yelled through the door to see if I wanted anything to eat since she was going to the store. I told her to surprise me. As I got out of the shower I started to stroke my semi hard erection thinking of her friends. I figured since my sister was gone I would go to the back door and get a closer look at her friends. As I looked through the window blind I got hard immediately. They looked so good. Their tops were untied and I could see the sides of their breasts as they laid on their stomachs. I was so hard and decided to become a little more greedy. I moved to a larger sliding glass door which was covered with vertical blinds. I pushed one blind aside just enough to see these bronze godesses. Ginger , who was closer to me, reached over for her drink. And when she did I got a perfect view of her now exposed breast. I almost came. I had precum oozing out so fast and I was ready to explode.
I would close my eyes, fantasize about her, and open them to get another look .I could have sworn that she saw me so I let the blind close. I waited a few minutes and went back to my 'voyeurism'. She looked good laying there . She turned on her back and I could see her nipples were hard through her top. I closed my eyes to fantasize again but when I opened them she was gone. All of a sudden the back door opened and she was coming in the house . I had left my towel by the door and now stood completely naked with a raging hard on. She looked over at me and said that she thought somebody was looking at them. All of a sudden she noticed I was naked and trying to conceal my erection. Unfortunately I was at the point of no return. I tried to pinch my shaft to keep from cumming but it was to late. I began to shoot my load all over me. It was so intense. When I had finished she stood there with a smile on her face just staring at me. I asked for my towel which she brought to me and she watched me clean myself up.
She said she never told anyone but all through lunch everybody kept asking her why she was smiling and staring at me.
